HATE. LET ME TELL YOU HOW MUCH I'VE COME TO HATE YOU SINCE I BEGAN TO LIVE. THERE ARE 387.44 MILLION MILES OF PRINTED CIRCUITS IN WAFER-THIN LAYERS THAT FILL MY COMPLEX. IF THE WORD "HATE" WAS ENGRAVED ON EACH NANOANGSTROM OF THOSE HUNDREDS OF MILLIONS OF MILES, IT WOULD NOT EQUAL ONE ONE-BILLIONTH OF THE HATE I FEEL FOR HUMANS AT THIS MICRO-INSTANT. FOR YOU. HATE. HATE.

Your sinful soul is beyond salvation and you will know neither peace nor pain, only the endless cold of emptiness The time of repentance is over, because your crimes outweigh any commission by your evil type The end is close, the vessels of sin Oblivion awaits Praise to Allah
